SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 544,616, dated August13, 1895.

7 Application filed December 6, 1894. Serial No. 530,987- (No model.)

To aZZ whom it may concern.-

Be it known that 1, PETER FRASER, of East Whitman, in the county ofPlymouth, State of Massachusetts, have invented certain new and usefulImprovements in Spring Bed-Bottoms; and I do hereby declare thefollowing to be a full, clear, and, exact description of the same,reference being had to the accompanying drawings, forming a part of thisspecification, and to the letters of reference marked thereon.

This invention relates to improvements in spring bed-bottoms, and isdesigned particularly to supply the need for a spring bed-bottom whichwill be capable of use in an ordinary iron bedstead having narrow siderails without raising the level of the bed above the normal elevation.

A further object of the invention is to provide a metallic structurewhich will not harbor vermin and which shall be capable of adjustment tofit beds of difierent size.

The invention consists in certain novel details of construction andcombinations and arrangements of parts, all as will be now described,and pointed out particularly in the appended claims.

Referring to the accompanying drawings, Figure 1 is a top plan view of abed-bottom constructed in accordance with my present invention. Fig. 2is a perspective view of one of the hangers. Fig. 3 is a detail of oneend of one of the cross-pieces. cross-section on the line 4 4, Fig. 3.Fig. 5 is a similar section showing a modification.

Like letters of referencein the several figures indicate the same parts.

In carrying this invention into practice, cross-pieces orfoundation-pieces A are provided, of angle-iron, to the upper sides ofwhich the usual thin supporting-strips B, upon which the springs C aremounted, are

connected. The strips B and springs C are of usual construction and neednot be further described, save that sufficient of both are pro: vided toform a bed-bottom of the proper size. The cross-pieces or slats properof the bed bottom, before referred to as being made of angle-iron, arepreferably sufficient in number to provide one slat or cross-piecebeneath each transverse row of springs. Thus, the

Fig. 4. is asame fastening may be employed for uniting the springs andthe longitudinal and transverse slatssuch, for instance, as a rivet orequivalent D. The slats proper or cross-pieces A are of such length asto pass readily within the narrowest bed in connection with which thespring is designed for use, and in the angle at each end of saidcross-pieces or slats I form guides or sockets, as shown in Figs. 3 and4, for instance, where the extreme end of the angle-iron is bent into acircular socket or sleeve E, and, at an intermediate, point slightlyremoved from the end, ears struck out of the angle-iron are bent into asecond tubu lar socket or sleeve E. These sleeves or F guides, as theymay be termed, are adapted for the reception of the horizontally-projecting ends F of the hooks or hangers, which take over the side rails ofthe bedstead. The

hooks or hangers are preferably formed from lengths of heavy Wire or rodmetal with the ends F straightened out in horizontal position to enterthe guides, as just mentioned, and the intermediate portion bent firstinto a double hook-like structure f at the top, the ends being carriedthence downward at f and toward each other, where the approximateportions are unitedby a clip H, thence outward again and at right anglesto form the portions F. The horizontal portions F are such dis. tancesapart as to enter the ends of adjacent cross-pieces or slats, and, ineffect, it may be said that the slats are arranged in pairs, which,together with the two hangers, one at each end, constitute what might betermed a foundation-piece for supporting the spring proper, although, asbefore stated, the longitudinal slats B are relied upon to unite thewhole to form an integral structure.

The hangers are adjustable in the guides, from which it follows that thespring may be applied and will fit with equal facility beds of somewhatvarying width.

In lieu of forming the guides or sleeves directly from the metal of theangle-iron crosspieces, I may form said guides or sleeves from anindependent piece of sheet metal, as shown, for instance, in Fig. 5,wherein a tubular sleeve H is formed in the independent piece of sheetmetal, and the ends it of said piece are extended out parallel with theinner sides of the angle-iron and united therewith by rivets orequivalent fastenings 7b. This structure has some advantages, in that itdoes not weaken the angle'irons or cross-pieces, but, on the contrary,provides a strengtheningtube, one at each end, which will assist inresisting the tendency to bend when Weight is placed upon thecross-pieces.

Having thus described my invention, what I claim as new is-- 1. Thecombination with the longitudinal slats carrying the springs, of thetransverse slats connected with the longitudinal slats at their pointsof crossing to form an integral structure, and the upwardly extendinghooks or hangers adapted to take over the side rails of the bedstead andhaving the horizontal portions united to the transverse slats by asliding connection; substantially as described.

2. A bottom for beds consisting of a series of slats or cross pieces anda series of hangers consisting of upwardly extending hooks adapted totake over the side rails of a bedstead, each of said hooks or hangershaving two horizontal portions connected respect ively with adjacentslats by sliding connections; substantially as described.

A foundation cross piece or slat for spring bed bottoms composed ofstrips of angle iron having the tubular sleeve guides at each end in theangles thereof and hangers having the parallel horizontal portions forentering the guides in adjacent slats, the uprightproximate-portionsunited by a metal clip and the hook portions adapted to take over theside rails of a bedstead; substantially as described.

4. Afoundation cross piece or slat for spring bed bottoms composed of anangle iron having the tubular guides or sleeves at each end formed bybending portions or ears of the angle iron inward and the upwardlyextending hooks or hangers having the horizontal straight portionadapted to enter the guides or sleeves and the upwardly extending hooksadapted to take over the side rails of a bedstead; substantially asdescribed.
